HOME INSULATION AND SEALING IN New London
Whole-Home Insulation and Air Sealing for Homeowners Across New London
Most New London homes lose a significant amount of heating energy through attic bypasses, unsealed rim joists and gaps that were never addressed during original construction. Before an energy upgrade performs at its full potential, those losses need to be located and fixed.
Federal energy data suggests that properly insulating and sealing a home can reduce heating and cooling costs by up to 15 percent. We carry out a thorough assessment of where your New London home is losing conditioned air and address it with insulation and sealing solutions matched to its construction and age.
What Is Home Insulation and Weatherization Made Easy to Understand
What a Home Insulation and Sealing Retrofit Actually Does for Your Home
Insulation and air sealing correct two separate but related problems. Insulation slows heat moving through your walls, ceilings and floors, while air sealing shuts the gaps where outdoor air enters and conditioned air escapes. Most New London homes struggle with both issues.
Without proper insulation, heat generated by your furnace or heat pump passes straight through your surfaces into the cold outside air. Without air sealing, that same heat escapes through gaps around pipes, recessed lighting, electrical boxes and structural joints invisible to the eye but measurable with a blower door test.
In an older New London home, these gaps can amount to the same loss as leaving a window open all winter. We assess and address both issues before recommending anything, so the work we do actually delivers the savings it should.

What a Well-Sealed New London Home Gives You Beyond the Energy Bill
What a Properly Sealed New London Home Offers Beyond the Energy Bill
Most energy upgrades add a piece of new technology to your home. Insulation works differently. It shrinks what your home needs in the first place, and that reduction compounds every single winter.
A properly insulated and sealed New London home needs less energy to stay warm through the coldest months. That lower baseline means every other system in your home, be it your heat pump, solar panels, or battery, performs against a smaller target and delivers more capacity as net savings.
Residential heat loss is still one of the largest controllable sources of carbon emissions in New London. Improving your home’s thermal envelope creates a permanent reduction in that output. Unlike equipment, it doesn’t degrade or need replacing.

Frequently Asked Questions
Honest Answers to the Most Common Questions AboutInsulation and Air Sealing
We know improving your home’s insulation is a meaningful investment. Here are straightforward answers to the questions New London homeowners bring to us most before moving forward.
How do I know if my New London home needs more insulation?
The most common signs are heating bills that seem high relative to your home’s size, rooms that never reach the thermostat setting no matter how long the heat runs, cold floors in winter and drafts near outlets or baseboards. Older Connecticut homes built before the 1980s frequently fall short of current R-value recommendations and have never had air sealing work done. We conduct a full thermal imaging and blower door assessment to identify exactly where energy is escaping before recommending anything.
What types of insulation do you install?
The right insulation type depends on where it is going and your home’s construction. We install blown-in cellulose and fiberglass for attics, spray foam for rim joists and hard-to-reach gaps, and rigid board insulation where appropriate. For New London homes, attic insulation is typically the highest-priority area given the heat loss that occurs through the roof plane during winter. We specify materials by R-value requirements for New London’s climate zone rather than defaulting to whatever is cheapest to install.
Will the work qualify for Energize New London rebates?
In most cases, yes. Insulation and air sealing improvements to Connecticut homes are among the most commonly eligible upgrades under the Energize New London Home Energy Solutions program. The rebate amounts depend on the scope of work and your utility provider. We identify every incentive you qualify for during the assessment and handle the paperwork on your behalf so you receive the full benefit without having to navigate the program yourself.
How disruptive is the installation process?
Most insulation and air sealing work is completed with minimal disruption to your daily routine. Attic insulation does not require access to living spaces. Rim joist sealing is done from the basement or crawl space. In most cases you do not need to vacate your home during the project. We discuss the specific access requirements for your home during the assessment so there are no surprises on installation day.
Will better insulation affect how my home feels in summer as well as winter?
Yes, significantly. Insulation works in both directions. In summer it slows heat from entering through your attic and walls, reducing the load on your air conditioning system and helping your home stay cooler without additional cooling output. Many New London homeowners notice the difference in summer comfort almost as much as in their winter heating bills after a full insulation upgrade.
